Howzat Hospital

Aside from the memories of umpteen Ashes losses, the turf at Lord's Cricket ground rests above a series of disused railway tunnels. While we'd love to see them opened up for nighttime jaunts, smarter heads have proposed they be turned into a subterranean hospital. The £100m care centre would be attached to nearby Wellington Hospital, and include a suite of operating theatres and intensive care units. We'll leave the question of recuperating from serious injury while you're already (more than) six feet underground to therapists.
